Hadith 1014

Narrated Ibn 'Abbas (RA): Allah's Messenger (SAW) said, "Allah will not look at a man who has intercourse with a man or a woman through the anus." [Reported by at-Tirmidhi, an-Nasa'i and Ibn Hibban, but it was considered to be defective for being Mawquf (saying of a Companion, i.e. Ibn 'Abbas)].
